Thread: Corrugated pipe

Quick question. Just about to complete my job on burying my own downspouts. I used corrugated pipe. Ran it 200 ft to the woods and day lighted it there. I know PVC works best but based on the length I went with corrugated. I had to use an NDS y connector about 130 feet away from the house. I noticed when I ran water through it to test it I get a small drip out of the y connector. Is there anyway to seal these connectors? I ended up calking it and duct taping them then back filled the area around the fitting with crushed stone.
I have one more of these y connectors and looking for a better way like possibly roofing cement?

Corrugated pipe is not meant to be sealed before backfilled. I did a ton of research on this during my last irrigation job. Once the trench is backfilled, the compaction is suppose to create the seal. I used 9x9 drain basins last time, and used blackjack roofing tar to create a water tight seal before backfilling the trench (for testing purposes).
